I felt Koisuru Keigo 24 Ji like a Japanese series made in Korean style.

It is full of sweet moments, a bit of tension, some misunderstandings, yet everything quite foreseeable.
The story is interesting enough, the acting quite good and the leading actors very sweet.
It could have been a summer drama, that is an easy and enjoyable one. If you are looking for this kind,
it will probably be hundred percent worth its watching time.
